Bus bar and manufacturing method thereof

Abstract

A bus bar and a method of manufacturing the same may include a first metal portion made of a first metal material; and a second metal portion made of a second metal material different than the first metal portion. The first metal portion and the second metal portion are coupled by a rotation friction welding (RFW).

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2020-0115883 filed in the Korean Intellectual Property Office on Sep. 10, 2020, the entire contents of which are incorporated herein by reference.BACKGROUND(a) Field of the Disclosure

[0002] The present disclosure relates a bus bar and a method of manufacturing the same. More particularly, the present disclosure relates to a bus bar and a method of manufacturing the same made by a rotation friction welding (RFW) using different materials.(b) Description of the Related Art

[0003] In recent years, environment-friendly vehicles, such as electric vehicles or hybrid vehicles, are driven by a drive motor operated by electrical energy.

[0004] Since such vehicles are very heavy, it is necessary to increase the output of the drive motor to accelerate at high speed.

[0005] The output of the drive motor is determined by the magnitude of the applied voltage. The output of ...
